Fig. 24 D, E) ; the smaller setae are broadly fusiform, apically slightly pointed, 
finely ciliated and up to 16p long, on the propodosoma laterally the latter setae 
become more elongate and reach 40, in length (Fig. 24 G), the palpal femur and 
legs dorsally are furnished with foliate ciliated setae as in C. wyandrae. 
Loc. A single specimen from Flinders Chase, Kangaroo Is., South Austra- 
lia, Dee., 1984 (H.W.). 
Remarks. Differs from other species in the form of the dorsal setae. 
CAMEROTROMBIDIUM CARDUUM Sp. nov, 
Fig. 24 H-I. 
Description. Clothing dorsally of two kinds and sizes of setae: the larger 
globose and thistle-like (Fig. 24 1) with a basal septa, a strong whorl orally of 
long ciliations, and with longitudinal rows of long strong spicules, 50-70. in 
length ; smaller setae, 40, in length, with a large irregular head of strong but short 
spicules as in Fig. 24 H. 
Loc. A single specimen from Mundaring, Western Australia, Feb., 1931 
(H.W.). 
Remarks. Of this specimen only portions of the dorsal cuticle are now ex- 
tant, but the two forms of setae are so distinct from other species, that one ven- 
tures to describe it briefly as a new species. 
CAMEROTROMBIDIUM RASUM (Berl., 1910). 
Microtrombidium (Enemothrombium) rasum Berl., 1910. Redia, 6, (2), 361; 1dem 
1912, Redia, 8 (1), 189. Fig. 89. 
ROBENSIS Var. nov. 
Fig. 25 A-E. 
Description, Adult. Shape as in C. simile, with a distinct posteriorly con- 
vex suture between propodosoma and hysterosoma. Colour in life red. Length to 
1-8mm., width to1-:2mm. Crista linear, to 420» long with subposterior sensillary 
area at about 34 from apex, sensillae ca. 150, long, filamentous and apparently 
nude with bases 50% apart. Eyes 2+-2, on well defined sessile ocular shields. All 
legs except IV shorter than body, I 1650y, IT 1260p, ITI 1080u, IV 2000., tarsi I 
elongate oval, 360n long by 160” high — ratio of 3-11, metatarsus I 280, long, 
ratio of length of tarsus to metatarsus = 1-28. Palpi as in Fig. 25 B, stout, tibia 
with stout apical and accessory claws, two pectines and a single strong, fairly 
stout external spine arising near base of tarsus; tarsus slightly clavate and slightly 
exceeding tip of tibial claw. 
Dorsally setae uniform, small and globose, with apical opening and fringe of 
ciliations, otherwise uniformly ciliated, 24» long, and arising from a rosette-like 
pedunele of about the same height; when carefully examined from below these 
setae are seen to be formed of a scale in which the lateral margins have been 
folded to form the globose eup-like head (see Fig. 25 D) ; near the apex and sides 
of the propodosoma are some longer, 40n, ciliated setae as in Fig. 25 EH. 
Loc. Type and one paratype from under log at Robe, South Australia, April 
and Oct., 1943 (H.W.). Another specimen from Flinders Chase, Kangaroo 
Island, 8. Australia, 6th Dec., 1934 (H.W.).
